Thrust Sensor = CEL P0089

CaptainCalf · Apr 5, 2011

In case anybody has what seems like motor skipping and momentary power losses or some more pronounced fuel cut feelings while boosting and gets code# P0089 there's a high probability the Thrust Sensor on the high pressure fuel pump has gone bad.

From what I've gathered, the original part is susceptible to fuel intrusion and I think VW recognized it in 2008 with a technical bulletin and corrected the problem with the part. The new part has a new part number...RC

good to know :thumbsup:

I believe this is what went on my car. It's at the dealer now. I got fuel cuts even off boost and at low throttle positions.

I'd beat that it's a bad Thrust Sensor cuz it controls low pressure side...

$68 DIY, but pls let us know what the dealer charges...RC

$67?! Daaaaang. I got mine for $52 or something like that from the dealer when I had my APR pump. I guess prices have gone up due to necessity?

Yep, just depends on where you buy it cuz if you can wait for it you can buy it at ECS for $48.72+shipping: http://www.ecstuning.com/Volkswagen-Golf_V--2.0T/Engine/Fuel/ES251666/

Well damn. Nothing like profiting off of an engineering flaw to make it a good day. Good job, VW. Lol.

Dealer says they can't find what's wrong with it so I'm going to get it back and see if I get the CEL again (It turned off the morning I take it to the dealer, go figure) If it does, I'll replace the sensor.

Blaster · Apr 5, 2011

They also gave me some bullshit about a CEL not being under warranty and they want to charge me like $270 to keep it there another day. So that's not happening.

LOL, you gett'm Blaster!

Post up your next CEL and we'll help you fix that baby

They changed the timing belt tensioner under warranty and did the recall on the airbag sensor.

They did however charge me $107 to get the codes off my ECU... THAT I GAVE TO THEM ON PAPER. So basically they charged me for nothing. Can VWoA help me with this? :|

I doubt you'll ever get any of that $107 back, but for future reference auto parts stores such as Advance will read and clear codes for you for FREE!

I have a VAGCOM and I took the codes out myself and printed them. I showed it to them and I told them that I thought it was the thrust sensor. They didn't hear any of it and charged me to "diagnose" my car . Which was just to get the codes off of it, that I left for them on the passenger seat.

Doesn't work that way. VW won't reimbuse from YOUR print outs. You can make a print out read mostly anything you want. Pull the connector off a coil and see what the print out reads. Doesn't mean the coil is bad.

Blaster · Apr 7, 2011

They read the codes and got the exact same thing I gave them. They wanted to charge me $260 to keep it there another day for "further diagnosis" or some shit.
