P0236 + P0237 = limp mode (searched, been there done that)

Hey guys,

A quick background on my car: 2004 Jetta BEW TDi

I replaced my turbo actuator a few months ago due to the same fault codes, and would give me limp mode until the car was turned off, and turned on again after some driving.

This time, after clearing the codes, the car always is in limp mode (even after clearing the codes, with or without a CEL). Last time, the car was somewhat driveable until the limp mode cut in, now it's 100% of the time in limp mode.

Would this lead me to check vacuum lines first? Or N75?

The P0237 fault code came on first, after cleared a few times then the P0236 would be added.

Thanks for any advice in advance

This morning after clearing the codes, I was able to drive the car for about 10 minutes without a CEL or limp mode.

Can I assume I don't have a vacuum leak?

You need to systematicly go thru process of diagnosing limp mode- check my signature for a link to canadiangrizzly's write up on this.
