it will probably be ok - I would keep an eye on the engine bay to watch for oil coming out of the cap. The part is available from audi - they will likely have it in stock - but make sure you get the later part number ( on a T reg audi / your dealer will likely order the part to match what is...

There are two fans - one big (on a viscous coupling, the other small and with an electrical connector. The big one is running - this is what I believe to be the main engine cooling fan. The smaller fan is what I believe to be the aircon fan. This doesn't run. The compressor appears to run fine...

Have done a little more digging .. Vagcom thinks the compressor is running. Measuring Block 001 shows this based on the following label file. Mine shows 0, and then 6 if I press ECON, or 7 if I turn it off. When driving if I put my foot down it shows 12 , which is off for 12 seconds when...

Hi - thanks for the reply. My car (2.5 tdi) has main engine fan and then smaller fan on drivers side of car (on std UK RHD car). The engine fan is on a viscous coupling but is running from idle. The aircon fan is not. I have tried swapping out the aircon control panel with another one but no...

My A6 aircon has also just stopped - no cold air and there isn't the usual noticeable drop in revs when switching econ on / off so I'm assuming the compressor isn't kicking in. I've checked having read on here and the condenser fan isn't running (though the main engine fan did run...

I've got an oil leak on AFB 2.5 tdi A6 (175K miles). Audi changed timing belt at Christmas and advised the leak was from the upper sump gasket and quoted to fix that. I've now had the gaskets replaced - but by my local garage ( not audi) and the leak is still there. My local garage now...

It's not the crankcase breather ..I've already replaced that twice (last time with the newer version) , and in any case the symptons are not the same ...with that I had white smoke at idle. This issue was dark grey / black smoke and was when driving with revs sub 2k. The fix I found was simple...

Hi - my A6 has the 2.5 TDI 150BHP engine. It's done a lot of miles now (170K) and has started to smoke a little. It doesn't do it at start up but it's noticeable in evening traffic at sub 2k revs. Smoke is dark in colour. No loss of power - other than an occasional slight judder at around...

Mine is leaking - was a little now quite a lot. Audi say it's the upper sump and want £360 to do it ( car is an early A6 2.5tdi (AFB engine))... Any tips on fixing this...is it simply a gasket or does it need silicon sealant ?

...and I've got a 98 A6 avant with folding mirrors (and memory seats) -so can confirm that Audi did do them right from the start of the model and also I can confirm that to retract the mirrors the mirror adjuster turns 180 degrees to a picture of a retracted mirror .........and if left at the...

Self amalgamting tape has worked well and stopped the leak - so thanks for the advice ...just need to now locate the part number so I can order a replacement pipe for a permanent fix.

Thanks...will give that a try short term....

Hi, I've got a slight leak in the fuel line just forward / below the tank and I need some help in identifying the part ( I can't see it on vagcat) as I can't get to Audi until the weekend but would like to order the part now if I can. I'll try and describe what I have - essentially this is...

Just to update - I got the newer part as suggested in this thread and had my local dealer replace for me. Just over an hours labour and all is working fine now - so thanks for the advice. Hopefully with the new part this is the last time I have this problem ...

Thanks for the advice Jason and Turkster... I think I will get the newer filter that's mentioned in this thread to try and avoid having to do this again in another years time. As an aside I can stop mine smoking if I keep the revs above 1000 when sat in traffic. I wonder if by doing this it...

Not the EGR valve - mine is a blocker crankcase breather again. I won't be paying Audi to do it again - but I will try the newer part. Do you think this is a job I could get a competent friend with tools to help with - or are there specific tools neeeded ? Also - as a guide how long would...

I have replaced the crankcase breather on my 98 A6 2.5tdi quattro about 12 months ago - but the other day the white cloud started again. I've read all of this thread and see from Jason that the EGR is a likely culprit ( but then also that the crankcase breather could be knackered again). One...
