I have a 97 300tdi es auto which has been chipped (ecu model), cat removed, big intercooler, egr blocked off and hi-flow filter and I never get above 26 mpg. 80% of my driving is 60 - 70mph on motorway.

It's the green one behind the side panel in the passenger footwell on my 97.

You're right it is scary. In fact it can be pretty depressing, especially when you're doing around 1000 miles a week as I was until recently. Funny how they all vary tho. I had a 95 300 manual and I was lucky to get 24 mpg out of it. Good luck with yours, it'll be interesting to see how you...

Same thing happened with me although the sunroofs leaked aswell. I claimed a new screen with my insurance and it just cost me my excess. It was a heated screen but the cost to me was still the same. The sunroofs I sealed carefully with black silicone mastic. Mine was only on the outer seal...

I guess it's like anything mechanical, if you nurture it, it should last. I did hear of a pug 309 with over 500,000 on the same lump when Top Gear did a survey once. It's largely about care and servicing after all.

Fair play to him. A motor can only get SO loose before it becomes TOO loose and needs a rebuild. Be surprised if his motor hasn't been rebuilt which would obviously take hime back to square one as far as loose is concerned. Seems a bit optimistic on the same engine but I guess it's...

No. I felt more power but the MPG is the same. I now have a later ES auto with all the mods incl an ECU chip and all the other bits mentioned above but the MPG remains the same.

My 300tdi auto returns 27/28 on reasonably long trips (80-100 miles) and 25-26 towing my 20' caravan. I've done 16000 miles in it and never had 30mpg yet.

The Exhaust Gas Recirculation valve does just that. It recirculates part of the exhaust gases in an effort to achieve less emissions. If you remove it and blank it off with a plate costing 3 or 4 quid it will make the engine run cleaner and allegedly more economically. I did it on my last...

S368 VOP you are a bloody life saver. I have been tearing my hair out for two weeks with a similar problem to our friend here. I replaced the MFU which cured all except the rear wiper. I have replaced almost all the wiper bits incl a new motor, switch relay etc and all to no avail. Just run...

OK...latest query for you knowledgeable bunch!!! Anyone know where liveth the Rear Wiper Control Unit on my 97 300TDI ES?? In my quest toobtain the perfect working rear wiper I have>>>> Replaced the MFU behind the fuse box. Cleaned all the earting points. Replaced the switch...

That's funny cos I'm not sure whether they're supposed to be that way or not. When mine was working it sometimes worked only with door shut and sometimes not at all. I've just replaced the MFU under the fuse board and that cured most ills but the wiper is still holding out on me. Now ordered...

Battery seems to be holding its charge OK although I haven't drop tested it or voltage tested the alternator. I've ordered a new wiper motor from a guy on ebay (£36 delivered brand new). Also got a new switch, relay and a few other bits I need from somewhere else. Changing the spare wheel...

Can anyone tell me where to find the relay for the rear wiper in a 97 ES please? Also, does it serve the rear washer too or is it stand alone?? I can't get the rear wiper to work on the car but the washer is OK. If I put live and earth to the 2 terminals on the wiper motor it works fine...

Try again...Ignore my last. If I put test lamp wires in terminals 1 and 2 of the 3 pin plug, (left to right as you look down at it with the spindle towards you) the lamp lights as soon as ignition is switched on and switch does nothing. If I connect it to terminals 1 and 3 or 2 and 3, there...
