[MBZ] VW TDi question
A brother sent me the following query regarding his VW TDi: I had my VW Beetle TDi serviced at 105,000 miles. The fuel filter was replaced ($90.14) as well as the mass air flow sensor ($358.08). The service advisor also recommended replacing the exhaust manifold which is clogged with carbon deposits ($745.00). The engine has been sluggish lately, so I don't doubt the diagnosis. I was wondering if you have experienced similar problems with your M-B turbo diesels. Any advice would be appreciated. TIA, I'll forward any knowledgeable suggestions to him. G. M.

Re: [MBZ] VW TDi question
Tell him he should ask the dealer to go for a ride on his new boat. I suspect it's a big one. My sister-in-law has 2 TDI's. The fuel filters cost $30, Air Flow sensor is $100. -Dave Walton On Nov 27, 2007 10:41 AM, Glenn Brown [EMAIL PROTECTED] wrote: A brother sent me the following query regarding his VW TDi: I had my VW Beetle TDi serviced at 105,000 miles.

Re: [MBZ] VW TDi question
A bad mass air sensor will cause the car to be sluggish. The computer does not inject as much fuel as it should. Same thing happened on my 99 E300. I pulled the engine on a 2001 Jetta TDI to replace the transmission. From what I saw, carbon does not accumulate in the exhaust manifold. Those cars a real PITA to work on. Everything is squeezed in with very little room to work. I much prefer the MB's. -Dave Walton On Nov 27, 2007 10:41 AM, Glenn Brown [EMAIL PROTECTED] wrote: A brother sent me the following query regarding his VW TDi: I had my VW Beetle TDi serviced at 105,000 miles.

Seems pretty silly and expensive to me. He should probably look around for a good indy. The VW TDIs, at least the late-'90s 1.9 liter engines with which I'm familiar, are notorious for clogging the manifolds with soot due to overzealous EGR, much like the 603 engine. They can indeed be cleaned. It's not difficult, just time-consuming and messy. Like John says, find a good indy mechanic---anyone with TDI experience will be familiar with the process. Will cost a few bucks but not as much as brand-new manifolds (typical dealer solution---like burning down your house to get rid of a termite infestation!).

Re: [MBZ] VW TDi question
I believe the computer requires more trickery in order to disable the EGR. IIRC, the computer throws a fault code and goes into limp mode if it detects that the EGR is no longer functioning. I'm sure some of the 'puter wizzes over at the TDI Club have figured out a way around this by now.

You must be referring to the VAG-COM software. I don't think it's quite that much, but maybe so.

Re: [MBZ] VW TDi question
Speaking of VAG, when I was at that VW shop closing auction, I bought this big case of cables that says something like VAG 1598 or something like that. I will take a picture but what the hell is it. If I cant use it on anything MB, I will probably ebay it. --- Kaleb C.

Re: [MBZ] VW TDi question
The problems your brother describes are well-known issues with VW TDI engines. You didn't include the year of the car, but the solutions mentioned below are applicable to the non-PD engines (115hp, not 130hp) produced until about the end of the 2003 model year. There may be similar fixes for PD engines. The Bosch MAF sensor fails with regularity. I had three in my car in less than 50k miles. The solution is to use a Pierburg alternative, available from your local MB dealer. It is cheaper and apparently doesn't fail like the Bosch units, which are so sensitive that even an air filter changeout can release enough particles into the intake stream to damage the sensor. In Europe, the Bosch sensor failures were a huge problem affecting all diesels that used Bosch MAFs, which was almost everyone except MB and the French manufacturers (who use Pierburg or Thomson sensors). The other chronic failure, clogging, is actually the INTAKE manifold that is clogged, not the exhaust. This is caused by soot from the exhaust gas recirculation (EGR), which mixes with oil from the positive crankcase ventilation (PCV) and causes heavy deposits on the intake manifold walls. It also can prevent starting of the car when what VW calls an anti-shudder valve (ASV) in the intake manifold jams with soot. The ASV is activated when you turn off the engine, and is basically a choke flap that cuts off airflow at the same time the fuel is cut. The soot buildup can jam the valve, preventing the engine from starting. This happens with no warning, and unless you know what to look for (and wiggle/smack), you may be stranded. The intake clogging can be reduced through reduction of the EGR duty cycle. This can only be done through the car's VAG-COM interface. You can reduce oil fouling from the PCV by installing another MB part, a brass coil used on M117 gas engines, and known as a flame arrester. It is about $5 and easy to install. (Pic attached) I will post more details about what your brother needs to do, but there's lots of info on tdiclub.com. D. PS: As a preventive measure, if your brother ever has the timing belt changed on that car, he should ask to have the engine mount bolts physically returned to him in a bag. This will ensure that NEW bolts are used. They are stretch bolts (single use) and will FALL OUT if reused, leaving your oil pan and engine dragging on the ground!
