Lol... Is it bad when engine problems are called out by your username because you were the unlucky SOB to endure two of the same failure with no clear causality?
Lets see...
1: Yup, killed the EGR with the SEGR device in the first week I owned the CRD. Didn't seem to help with regard to the engine failures.
2: Yup, had that too. EHM solved it, but I didn't like the drooling either.
3: Yup, installed the Mr Gasket fuel pump back by the tank (need to do this on my TDI) and solved that problem permanently... Until the fuel pump spat off it's OWN front end, and dutifully sprayed about 5 gallons of diesel onto the ROAD before the thing quit running and I figured out what happened.
4: Yup... Inline thermostat fixed that, and I plan on the same for my TDI if it ever needs it.
5: Surprise! Never had an issue.
6: Yup, changed them both (only one was really bad) and whoever designed the mounting location for the driver's side... Needs to spend the next 20 years counting trees in Siberia. In their underwear.
7: Surprise! Apparently also never had an issue in 130k miles and 2 engines. Rockers were only damaged by monkey replacing engine.
8: Surprise! Head gasket was just fine on both engines. Too bad the engine under it wasn't so good.
9: Don't know, didn't know about this problem initially when tearing down my motor. Doubt they were bad though, but I HAVE found at least 2 or 3 on each engine that I have worked on that are NOT PROPERLY TIGHT from the factory. This is a troubling thing to discover.
10: The MAP got cleaned a couple times, but with the SEGR, the only thing on it was wet oil. No sludge.
11: Never had an issue with the ceramics on my own engines... WILL NOT change them on anyone else's after a massive problem from the #3 snapping off just as it was coming out of the head. No damage... But LOTS and LOTS of work.
12: Had this problem. Ah, whatever. Cheap Chinese trash part. Replaced it on lots of vehicles.
13: Yeah...

14: Had 2 turbos fail, BUT the engine problems didn't seem to be caused by that after engine #2 killed itself without ever running low on oil OR oil pressure.
