4.2 TDI problems
Posted: June 14th, 2021, 1:30 pm
Hello all,
Purchased a new (demo) C37 back in December. New boat with VW 4.2 TDI engines.
I cannot believe how many things were bad from day 1.
Isotherm tripping breaker, line through a TV, Grill switch malfunctioning, and a low fuel indicator on the vessel view with a full tank, limp mode after 2500 rpm one engine. Months later after everything (except the engine error ). The mechanics found a non punched out knockout in the return line to the lift pump. So now the think the fuel injector pump is bad. Of course, to make matters worse, this part is out of stock for possibly 2 months!!!
So much for this years boating season.
Has anyone had luck with these engines? The worst thing Mercury did was have the mechanics swap parts and harnesses. That made matters worse.
The boat is in Florida and I planned on taking it home back home to Boston in April. I feel like this was the biggest error in my life right now.
