    Thanks guru for the advice on the belt tension re the A4. This was the first thing my nearby Audi-trained mechanics checked, as well as plugging in a code reader. They believe, as of today, that there is an air intake regulator valve of some type they will need to replace. We alos note fuel consumption is up dramatically during the period they tested it...something like 3MPG based on the fuel used in the hour or so they had the car running for tests. Nuts?

Hi,
the squeal is caused by a belt,not tensioned correctly ,I would check the cambelt tension first and then the serpentine belt,if not obvious you need to take to a Audi trained garage.If you plug in a code reader it will help point you in the right direction by the fault code.

A6 turbocharged. Whyu does it smoke when it covers a 120km per hour?


I am going to say 'blown turbo'. As I understand it, they needs replacing every few years. They are susceptible to heat and incredible revolutions. They have to be lubricated, the seals go, and you get smoke.

Check engine light came on while driving, now when you accelerate it makes a loud hissing sound and is sluggish. Can I drive it this way for 200 miles to get it home or is there something serious wron


Is this a Turbo model? If so, it sounds like you have a blown Turbo or a leak somewhere in the turbo system. 200 miles is a long way to go with a bad part, and it's pretty risky. I'd get it checked out by a local mechanic before trying to drive that far.

Audi A6 3.0 tdi Quattro 2005, glow plug light comes on, limp mode


16619 -Engine boost condition - Limit not reached. Check intake hoses/ connections for leaks. Check Turbo charger waste gate regulating valve/ waste gate working correctly. Must move freely when accelerating, won't achieve full boost if waste gate sticking open. Check Turbo impeller turning freely, oil feed pipe for turbo can get blocked causing impeller to seize. Engine compact, not easy to access these components.

Removing turbo from audi tt 225 quattrro


Yep, it is possible to get turbo off without pulling engine. I had a TB break at 85000 miles and did the repair at home (2 bent exhaust valves, 1 intake valve). Getting the turbo disconnected from the exhaust manifold was the single toughest part of this repair. It is attached with 3 reduced head socket bolts (appear to made from stainless steel). Eventually had to drive out one of the bolts...

2002 Porsche Boxster - had squealing coming from


Mine did that off and on for a month with no other problems then it started making a loud suction noise and the check engine light came on. I took it to the dealer and they said the "oil separator" needed to be replaced.
After the repair I never heard the squealing again.

Turbo= not working


Most likely the turbo is gone. What ever part of the turbo went, just replace the entire turbo. Not serviceable 99% of the time. The engine will not like being driven for any extended period of time with a bad turbo.
