    Question 09 2.0t CCTA VW GTI - throttle body issues?

    The other day I noticed that once in awhile the car would kick a bit when engine load changed - it almost felt like a bad engine mount, but would only do it on occasion. Later on that day I came to a stop sign and the car went into limp mode. It had a hard time idling, it was hunting. It responded to the throttle just fine though. I pulled the codes and saw what was listed.

    I checked the connector on the TB to make sure it wasn't taunt, unplugged and plugged it back in.
    I checked measuring block 62 and all looked good. The pedal angles looked like what they're supposed to all through the pedal travel
    I unplugged the MAF to see if that would make any difference and it didn't
    I did a TB adaptation and that made no difference
    I figured unplugged the MAF might have thrown a new code, so let me clear everything and see what's still in here. As soon as I did that the car runs normal. Did a 15 minute drive around town and it's still good.

    I know something is going to die on me at the worst possible time so I'd like to find the root cause of this. Any guesses?

    Before clearing codes what are the long term fuel trims at idle and part load?
    +or- 5% is good.
    Also TSB for Throttle Body harness would be a good guess for P0121, P0221 & P1545

    Also check your PM I left you one.

    Good Luck

    Take a look at the wiring harness and connector at the throttle body itself. There was an updated terminal housing and terminals for the throttle body. The wires were cut, new wires crimped in and taped up. This was to fix a poor electrical/mechanical connection at the throttle body itself that can cause those types of fault codes.

    I did a quick bit of searching and found this:
    https://f01.justanswer.com/mike2765/...rottle+tsb.pdf

    Verify with your local VW dealer that the part numbers provided are applicable to your VIN.

    When this repair is done, it is important to be 100% you don't get any wires mixed up... I did these one wire at a time, double checking the correct location of each wire before I went to the next wire to cut/crimp.

    Auto-Scan, learn it, love it, live it... then check the fuses.

    I drove the car 45 miles to work today and it was OK. I'll check the fuel trim later on.

    As far as the TSB, it hasn't been done on my car, but there looks like plenty of slack on the cable. From my understanding the issues was caused because the cable was too tight and the wires would be pulled out of the connector, right?

    No the pins in connector go bad.
    Very common even on older MK4 models but no TSB was ever made for them. They started to fail later in life with high mileage.
    MK5 failed at much lower mileage therefor the TSB was produced.
    And the parts are not cheap pig tail wires costly for just short pig tails.

    Good Luck

    Stan Lee Marvel Comics is correct ( VWTECH )

    When someone can't get the connectors, I have found that taking TV apart drilling holes and soldering wires to the PINS in the TV stationary and crimp clip, then route wires out & fill connector with RTV silicone and too extend the needed length to make new plug in safe area or back to ECU directly + a strain relief with spiral-wrap does a nice trick.

    Ah, ok. That sounds like it applies then. I'll look into doing that. I checked the long term fuel trim (for the 45 miles this morning) and idle was at -0.2% and load was at 0.8%.
