Hi All Aircon ECON light came on & stopped working, I found it had both Low & High Pressure faults, cleared those and still no joy. Got it re-gassed and compressor wouldn't start up, so the guy couldn't complete it & he recommended I change the pressure sensor. After fitting new sensor, back...

Sorry, I don’t understand that

I did use the 3Nm & 90 & 180 turns on new bolts. Thanks.

Sadly no pictures, I just started cleaning it up. It wasn’t “full”, there was just lots of oil on the surfaces and in the rotor and paddle. I had recently tested the vac system and it was pumping fine & the one way valve has kept the oil out of the vac tubes. I’ve taken it off to fit new seals...

That’s the same manual I have. I have a torque screwdriver for those tiny figures. I guess even 30Nm is not very tight so I wondered if the 0 had got omitted somehow. Thanks

Hi I just replaced the seals on the injectors on my 2.0Tdi 16V 170, engine code BRD. The Audi manual says the new bolts are tightened to only 3Nm before a 90 degree then a 180 degree final set. This seemed a very low torque setting to me and the bolts did not “feel” tight even after the angle...

Hi Suspecting that I'm getting oil into my fuel, I just pulled the tandem pump off with a plan to clean out & fit new seals. I was surprised to find the vac pump side awash with engine oil; so I figured the seals are well gone... or is this normal? Ian

Hi all I’ve got the same issue on A4 2.0tdi 170, engine code BRD. I’ve checked all the vac system for leaks and that actuators all work. I did replace the turbo control valve as it didn’t hold vac solidly when disconnected; but neither did a brand new pierburg one! I cleaned loads of gum out of...

Hi Sarah, thanks for that, I’ve been starting to think this was a fuel issue and recently bought a full set of filters and oil for an early service. The history with the car says the fuel filter was changed about 20k ago (of which I’ve done about 12k) and I think the service interval says every...

I just checked and although the ign off/on cleared this limp mode as usual; I did not get the p0299 mentioned above, or any other code recorded for this limp mode.

Hi I just had a run up a hill & got these readings of intake absolute pressure during a full throttle pull. At idle 97kPa Peak in 2nd 210kPa Peak in 3rd 235kPa Peak in 4th 190kPa but it cut into limp mode at this point. I make the boost figures as follows; 2nd 16psi 3rd 20psi 4th 13.5...

Thanks, I’ll see if I can get that from my scanner, but it’ll be next week.

Hi All Got the same on my A4 Avant 2.0TDi Quattro, engine code BRD. Limp would kick in when on motorway using cruise control when I hit a hill, as usual a ignition reset cleared the limp & a scan gave P0299 (i only have a simple scanner) I checked the vac system... Vac Pump; generating -28"Hg...

I’ve currently got a couple of A4 Avant Quattro workhorses which I’m planning to keeping going; a 2003 2.5 Tdi (180) with 215k miles and 2008 2.0 Tdi (170) with 140k miles and now a P0299 problem.
