MK6 Rattling engine under acceleration

[Louey]

Driving home yesterday, I pulled off from a junction and the engine was rattling and struggling to accelerate - MK6 2003 2.4 tddi
It had a new pump fitted in April, engine was a refurb/rebuild two years ago - not done a huge amount of miles.

Since the new engine I had replaced the fuel timing solenoid - the fuel pump came witha new one too. Always had issues climbing hills since replacement engine and sometimes the van would struggle to get to 55mph with the slightest incline. I would sometimes pull over, restart the engine and it would be absolutely golden.

Fault codes are P1666, p1564, p0149 - Don't know if I can do anymore than just find fault codes with Forscan.

Not fully sure where to start - can't get to the garage for a few days either. P1666 confuses me.

Just gone out to start engine and it rattled for a few seconds, pressed accelerater to rev engine and then it has cut out

How easy is it to check the timing chain? Is it a case of taking off the front of the van (rad, grill etc) or is there an inspection hole somewhere?

p1666 = Fuel injection pump - cranckshaft position sensor (CKP) synchronisation
p1564 = fuel injection pump - reduced fuel mode request
p0149 = Fuel Timing Error

I'd say your pump EDC and timing solenoid are not well. Would indeed pay to check the cam timing....would also pay to check the crank sensor.

I must have deleted the codes - oops. The breakdown guy came out this morning (only way to get it to the garage) and there weren't t any fault codes for the recovery driver to read. Is this significant or will the codes return.

His diagnosis was possibly the fuel filter or filter housing - because he didn't get any codes. Just waiting for the big truck to get it to the garage (less than half a mile way )
I'm going with chain or fuel pump/pump wiring.

Mk6 codes are notoriously difficult to read, it could be that his reader didn't pick up on them

Do you know what code reader was used..?? Mk6 machines aren't OBD-II compliant so most of the newer readers won't work on them.

Not sure what reader the guy had but he really didn't try much, I think he could tell I was wanting to go to a garage. I was using my laptop. Garage rang and the three codes came back up - he is currently checking the timing chain.........
