Re: Caddy 1.6tdi issue
100 kpa is 1 bar so your pressure is 400 bar. The issue may be the pressure reading is too high, not sure what the ECU would do in this situation

Re: Caddy 1.6tdi issue
hello, if the engine light flashes when the ignition is turned on, there is a possibility of a lack of communication with the on-board instruments, but the car lost power and stopped, so I think it is more likely a flow regulator (on the high-pressure pump) or a pressure regulator (on the injector rail). with a tester you can check the main parameters: engine speed 200rpm, rail pressure 250 -350bar, (after starting 1500bar) crankshaft synchronization with camshaft. another cause may be a clogged exhaust (you can loosen it or unscrew the lambda probe for checking) If one of the regulators does not work or the injector empties the rail and exceeds or does not reach the target value, it does not authorize starting or the engine stops. I hope some of the recommendations help!

Ohhhhh it’s turned into a disaster……
Turbo fins have snapped off, gone through the engine, bent atleast 2 valves so looks like engine rebuild or new engine jobby

Re: Caddy 1.6tdi issue
New engine. Took the head off the old one and one piston was battered to pieces and nearly all valves was bent.

Re: Caddy 1.6tdi issue
Pardon my ignorance but I struggle to see how the bits of compressor (small enough to go through the intercooler) could bend the valves.
Couldn't it have been a timing issue from the beginning?

Re: Caddy 1.6tdi issue
I also agree the shards of metal must be micro scopic to pass through the intercooler core make it past all that carbon on the inlet and into the cylindersJavito wrote:Pardon my ignorance but I struggle to see how the bits of compressor (small enough to go through the intercooler) could bend the valves.
