    2.5tdi. WOT hesitation and dash lights on

    Ok I've had it at a service agent. It's the 550 code that keeps coming up. MAS seems ok. The prime suspect according to the mechanic is the #3 injector, it has the wire coming out of it a needle valve sensor (sorry the correct name is eluding me). Trouble is that's expensive and is only a...

    AKE 2.5 tdi fault code 550

    My allroad has a nasty hesitation. 2.5tdi ake engine. 200k. The fault code that keeps coming back is 550 'start of injection regulation, value above upper control limit' This points to a fault in the injection pump, but I replaced that new about 20k ago, a suggestion is the needle lift sensor...

    2.5tdi. WOT hesitation and dash lights on

    My allroad has recently developed a problem at full throttle. I put my foot to the floor and a moment later the (AKE) engine begins to hesitate, it smokes, then if I hold for a second or two the ABS and ESP lights come on followed shortly after by the air suspension light. If I then back off...

    C6 3.0tdi reliability?

    ph, yours is a manual I take it? Just how does one check the clutch apart from driving it and feeling any wobbles/noises? Service history is easy. I'm assuming a 56 plate won't have the timing chain tensioner issues, as it was the earlier ones that were faulty? Adamss, I'm not familiar with...

    2.5 TDI V6 cambelt change - help please!

    It appears I'm about to remove my injection pump. My belts etc are less than half way through their lifespan so I figure to leave them be. So before I pull out the socket set... any advice on injection pump only transplant?

    Please explain the fuel system on a 2.5tdi

    Ok I have the numbers for the two injection pumps now... My pump Audi 0470506016, Bosch 059130106E His pump VW 0470506010, Bosch 059130106C What differences? Is it just the Electronic Diesel Controller, which is an easy swap? My car wouldn't start this morning again...Oh joy!

    C6 3.0tdi reliability?

    Looking at a manual 3.0tdi C6 allroad 2006. It's got 114,000 miles on the clock, which may, or may not, be a lot. Trolling around, these motors seem to get no mention of specific weaknesses, so just what can I expect it to do long term? Clutch/gearbox, drivetrain? Long term issues? The car...

    Please explain the fuel system on a 2.5tdi

    Thanks for the replies. I picked up the car today and according to the (accredited VW) indie who fixed it... The VP44 pump is the issue. I now understand that within the VP44 is a nother feed pump which sucks the fuel in and boosts the pressure up for the high pressure pump to send off to the...

    Please explain the fuel system on a 2.5tdi

    adamss, I think you are onto something here. I had to trailer the car to a indie and they have got it going. Now i haven't been and got it yet, but he explained, over the phone, that the issue is a priming one. He suggested the pump is of the earlier type and that the VP44 injection pump...

    Please explain the fuel system on a 2.5tdi

    Thanks for the replies. It's a 2000 Allroad. Auto, so no tow starting sorry. I wish it was a manual! The pump is definitely not stuffed... it sent a nice big fountain of diesel into the air when set up on the bench. As I said before, in the car the pipe comes out of the pump and then dives...

    Please explain the fuel system on a 2.5tdi

    OK. My car won't start. Scanned it.... nothing relevant at all. Cranking scanned it. Lots of data. Dunno what's relevant or not. I sent the data off to an indie. He said check the fuel pump in the tank. OK so I took the rubber hose off and turned the key.... no fuel. So I took the cover...

    2.5 tdi, a starting issue

    I have had a non start issue. 2000 allroad. If I absent-mindedly try to start the car (cold) without 'glowing it' and it (quite rightly) struggles to start. I then quit that start cycle and 'glow' as normal and proceed to crank. Nothing fires at all. Crank, crank, crank...not a murmur of...

    Any Allroads been remapped ?

    I have chipped mine (Inmotion chip) it's smoother, faster and more economical, so I'm pleased. You are quite correct regarding the slushbox, I sooo wish I had a stick-shift. What I do is put it in 'manual mode' and, when going up a big hill for example, I shift down to 4th and keep the revs @...

    Air suspension, nobody@home

    I have had my 2000 allroad off the road for many months due to a bizarre set of unfortunate incidents. I had a friend put in an Inmotion Chip (mines a diesel 2.5) that failed (no fault of Inmotion) and needed the ECU to go to Austria to be repaired. Anyway.. Now it's going again but the air...
