Mass Air Flow sensor

I have a 99 Golf Wolfsburg, 5 speed, 2.0 L with 91,000 Km. Westm#nster Volkswagon just replaced the plugs, rotor, cap to resolve the check engine light issue. VW advised the MAP sensor should also be replaced at a cost of $765 (Canadian). I have had a number of check engine lights over the past few months and have replaced the O2 sensor, evaporative canistor value, plug wires and now a MAP sensor. Would anyone know what the sensor looks like and where I would locate it. I would expect the MAP sensor to be located on the duct coming out of the air cleaner, however, I have never seen what one actually looks like. Are there any after market MAP sensors out there? I tried one of the local auto parts dealers (Lordco) and they were only able to find one produced for 2000 and up. I did not think the engine changed between the A3 and A4 and would expect the MAP for a 2000 would be compatible, am I wrong?

By the way the service at Westm#nster VW is very poor.

Please help :smile:

I believe you mean a MAF as your car won't have a MAP sensor. The 2.0 sensor is widely available and relatively cheap. Do a Google search on "VW 2.0 MAF". It is located at the outlet of the air filter box.

By the way that MAF should still fall under the 70K mile ?K kilometer warranty.

Unfortunately the car was purchased in late 98 and the manufacture warranty has since expired and the excellenct extended warranty does not cover emissions equipment. I am quite upset with Autoshield (extendend warranty) because the MAF is not an emissions device and thus should be covered.

My thanks. I am looking at unloading the car and getting a 2003 Jetta Wolfsburg in the next few days. (If all works out).

Cheers,

VW has an extended warranty covering the MAF specifically.

MAF sensor is not covered in Canada on the 1999 model.

Not to worry I just picked up a brand new 2003 Jetta 1.8 T Wolfsburg. The MAF sensor problem is someone else's problem now.

$765 CDN????? where the hell are you? North pole?
I live in T.O., and I just replaced my "MAF" sensor for $561 CDN for a
VR6 GTI. That one is the most expensive. Your MAF sensor should
cost WAAAAAAAY less!!!!! If I'm not mistaken I've been told the one
for the 2.0L (at least for years before '99) is only $90 or so.
...and for the '99 and older NON-VR6 engines, apparently there IS
an aftermarket sensor.

I got news for you... it's not only SERVICE that's lacking
at Westm#nster VW... "ALL" VW Dealers are rapists&butchers!
I feel your pain!!!

There are several internet sources now saying the VR6 and the 2.0 MAF are actually the same part. Some parts sites are now selling one sensor for both applications. There is a difference in the outer plastic housing diameter, the actual internal sensor that screws into it is identical & has the exact same Bosch part number. There has been alot of criticism about VW charging such a high price for the VR6 compared to the 2.0. I've opened some up & seen it myself.

There are several internet sources now saying the VR6 and the 2.0 MAF are actually the same part.

I was somehow aware of that when I bought mine for the VR6,
but with the luck I have, I figured it probably would die all the same,
and I'd be out the cost of the real VR6 MAF, sensor in addition
to the 2.0 MAF (experiment). - I wasn't willing to take a risk
without hard proof that they (the actual elements) ARE the same.

I must say Boschman, you are both knowledgeable and very helpful!!!

assuming you are somehow actually connected with Bosch,
I don't suppose you could answer me whether there is such thing
as a BOSCH repair depot that does "component level repairs"
on Automotive Electronics (NOT car stereos!) is there???
...and if so, is there one in Canada as well???

Thanks!

No, I'm not with Bosch GmbH. While I really like the man and the company as a whole, their electronics are the one item I really have come to despise in recent years. There are a few places that repaired older Bosch electronic components, usually ECM's. Most modern electronics are not under this category though, they are only replaceable. Smaller components such as sensors, switches, motors and relays have never been repair items as they were not high dollar enough for companies to be interested. That is not to say they aren't repairable, in fact many are easily repaired. Failures of things like bad solder joints or worn contacts are common on electrical components, it's the poor quality of the modern electronics where you get into trouble. Bosch provides sources to better understand their systems and with a litle electric/electronic knowledge you can learn to do some of these repairs yourself.
