Stone chips can be repaired quite successfully unless they are very old and contaminated with dirt, the screen does not need to come out unless it is to be replaced.

As above. But if it goes straight up to 3 with only the ignition on(engine not running) then the pressure sender is faulty.

Use a good quality semi synth 10/40 oil like Mobil 2000 or Shell Helix.
Thanks Stu and Gareth. I checked tonight and sure enough at IGNITION ON (Engine Off), the bars are all the way down. Once I start the car, it goes all the way up to 3. Funny enough, when I then turn the car off, it will stay at 3. But when I turn just the ignition on, it will drop to the bottom. So, I guess that is OK.

Been driving this bad boy quite a bit lately- love it.

1. Any recommendation on sourcing OEM springs? I want to get it raised to original height - existing springs have the car lowered 15mm and I am eager to get it back to original height.
2. Something funny is happening with the exhaust. At idle the bonnet does not vibrate at all - solid. But the rear of the car vibrates quite a bit -so much so that the rear door cards make noise and one rear panel vibrates. Quite a bit of noise from exhaust. Could this be rubber mounts that need to be replaced to secure the exhaust so it won't vibrate so much?

Thanks guys.

Well we did the same.
my dad bought his 2.3-16v which was lowered...
So the front exhaust was even broken because of it.
So we bought a set of second hand original16v springs, be sure to get the right onces! Then we went to the dealer and ordered the right rubbers ( 1dot till 4 dots) All depending on the options your car has.
Then use a original spring compressor, see pictures. The rear once can be done without compressor, by just using a garage jack. the front ones NOT!
You need to compress them 50%
I have pictures somewhere, will look for then, then you see the right springcompressor and how we did it.

Thanks Marcel - looking forward to the pictures. I think I have less than 40 points worth of options (sunroof, leather, auto) so I can use standard springs. It definitely needs to get raised. Not to mention the ride.

So, just started her up this morning and heard power steering noises with every turn. Drives fine but I can hear the whining when turning the wheel. Noticed spots on driveway this evening - so something is definitely leaking - I am thinking Power Steering fluid? My drive to work is about 20 miles each way - think it is OK to drive a few more days before I take it to AutoMerc in North London for a diagnostic?

Yes, I'm sure it will be fine to drive to work.... but before you start it in the morning, check the Power Steering Fluid Level.

Can you tell me where to check the fluid level? Facing the engine bay, I see fuse box far left, Coolant, Windshield Washer Fluid all on left side of engine bay. Where is Power Steering fluid to check/top up?

See the picture of the engine bay below, arrow indicates the power steering fluid reservoir.

Got to push the silver lid down before turning the cap!

Hope UK Merc Man doesn't mind me using his lovely engine bay for the pic, don't have one of my own :)

Thanks for the picture. So, my Cossie engine bay does not look like this at all. But I did find it under the air filter (?). It is a bit fiddly to get to so I am going to AutoMerc and have them top it up for me (Hopefully I can see how he does it and learn something).

The car does centre back after turning (or at least as much as you can expect a 23 year car to) so I don't think it is the ball joints (and it makes the noise on both left and right suddenly).

OK, so I am back from AutoMerc (super nice guys by the way). They topped up my Power Steering fluid only to have half of it on the garage floor 5 minutes later. After much convincing, I got them to raise her so we can have a look and it was quite obvious there was a big leak from the Kevlar-type hose leading to the pump. It is fiddly to get to and appears to need some dismantling of the coolant reservoir etc just to replace. So, £450 (incl VAT, parts and labour) and this should be resolved early next week. Had to leave her there over the weekend (did not want to risk ruining the pump as the leak was quite bad).

I could be wrong, but £450 is quite steep for a job like that. Like I say, I could be wrong.

Anyone else think the same?


At least it will be sorted.

£250 for labour. Not sure how much the Kevlar hose kit is but I also think it is a bit steep. But a MB-Club club member did a great write up on this garage and I did not have a MB specialist and of course this ended up being an emergency as it was leaking quite badly. Live and Learn I guess. You are right, at least it will be sorted. I will ask him again on Monday on the break down of the work.

OK, so a quick update on the Power Steering Hose issue. Replaced with new part (which incidentally does not look like the old part (had black kevlar covering and new part has silver aluminium looking housing). AutoMerc had to empty coolant (£30 worth), empty suspension oil (due to rear SLS and £35 worth) and empty power steering oil (£30 worth). Then had to remove all that to get to the house properly to replace.

Turns out my damper bushing had come lose very soon after I picked up the car so rat-a-tat-tat for 2 days to and from work - what a racket that little part makes - you would think my engine was about to give out. Got back to AutoMerc and sure enough the bushing was long gone - he happened to have a very similar used part handy do we replaced and all seems to be fine.

Since having the car up on the lift we found that the gearbox is leaking fluid (very slow leak but quite evident). Thought to check the fluid level and it was BONE DRY. Put 2 litres to top up and should be OK until I can get it sorted.

SPEAKER QUESTION: prevoius owner put an Alpine head unit in the car. Original speakers though. Only getting sound out of the front speakers. Rears are silent. I have removed the rear speaker grill (Blaupunkt Blue Magic speakers) but need a very small height screw driver to unscrew all four screws to get to the wiring I guess? Need to see if they are even connected.

There are a lot of unconnected wires behind the head unit. No idea for what. One set is for the iPod connection - rest not sure of.

SPRINGS QUESTION: want to get OEM springs put back on. How much should this set me back?

ENGINE MOUNTS: Are they easily to replace. When I turn the wheel sharp right - makes a whining sound - mechanic said it could be engine mounts on that side worn down. (??)

Thanks for the comments and advise everyone.

Great picts! Thanks for the information. I still have you down for when I get ready to replace my lap timer :-) I need a new outside temp gauge as well. It is working (as I can see the '+' on it) but bleeding badly so not really functional.

Anyone have any recos on a good stereo (that I can connect with a 6-disc changer perhaps) that looks OEM or matches the lighting in the car?

Hi Everyone - wondering if someone can help me out with this one.

Car stopped on me in central London a few weeks ago - was idling and just conked out. Tried started a few times to no avail. Then finally it turned over and I drove straight home. Parked and had not used the car for two weeks. Went to drive the car Friday and it cranked. I let it idle for a few minutes and it went out on me again and would not start. Today I went out and it started. Drove it for a few minutes up the road and back. Turned off and now it is not starting.

When I put the key ON without starting, I don't think I hear anything priming, pretty much silence. But sometimes it does start.

Any ideas or things I can try would be much appreciated. I am taking the car up to Star Motors in Reading (Ian Wright?) but that is a week away and I would rather drive it then have it recovered and towed up there.

Fuel pump relay! Can be cured sometimes by finding a dry joint and re-soldering otherwise call wunderpartz!

Check it by linking connections 87 and 30 on the socket. If the fuel pump runs when the ignition is turned on then the relay is faulty!

Thanks Big Ben. Silly question but does any one have a picture of the fuel pump relay as it sits in the engine bay? There is a relay right in front of the battery but it starts with ASD which makes me think it has to do with the differential (?). Mercedes want £190 for the fuel pump relay :-)

Thanks. Can someone SHOW me there the Fuel Pump Relay and OVR sits in the 2.5-16? I cannot locate it easily unless I have to unhinge/unscrew/break something off :)

This link (see below) may help, the FPR is the small black relay(with white writing on top) to the left of the larger ECU, the OVP is behind the FPR where you can see the red cover on the OVP.

Before buying a FPR would be best to carry out BigBens handy tip on shorting out the FPR pins (once FPR removed). Is easier to take battery out then remove the back plastic cowling that protects the ECU, FPR & OVP etc then short out pins as Bigben explains.

If link doesn't work insert "Fuel Pump Relay" in the search box.

Try tapping the top of the FPR with the handle end of a screwdriver while the ignition is switched on.This is easy to do without removing anything by just pulling back the plastic cover.This got me home several times when mine conked out before I got it changed.

Where can I find the FPR though :-(

Seems to be starting fine last few days and I can hear it "turn on" when I put the ignition ON (without starting the car).

Antenna needs replacing but its not a Hirschmann. Does that mean I cannot use a Hirschmann (is it an easy replacment)?

Contact Car-Masts UK and don't worry that's it's not a Hirschman: They'll have one that will suit. :D

Thanks for the referral Michael. I will be ordering a genuine replacement from their eBay store.

Guys - regarding my FPR woes. I found a post on here (http://mercedes-190.co.uk/topic/6578180/1/) which talks about the problem I am having. After reading the replies it made me realise another issue that MIGHT be related or at least will help trigger some suggestions from the more experienced of you lot.

So,the kickdown relay is on the FPR as well as I have an automatic. Just a month after I bought the car, everytime I used kickdown on the car, around 60mph, the car (and speedometer) would hesitate and try to rev higher but would not do anything - this caused the speedometer to jump frantically and then finally if I let go and eased the gas back on it would get up to the speed I wanted. It has been happening more and more consistently now whereas I can almost do it every time. Just after this symptom, my car would either stop at a light when idling or not start at all - hence my current issue.

So, does this all sound related? I will try to get the FPR out today and get it replaced. It is due to go to Star Motor in Reading soon so I want to sort this diagnosis out before I send it as I don't want to pay £200 for a genuine MB new from dealer.

Any advice would be great!
