hi i recently bought a high (92k) focus 1.6 tdci have found it quite rattly on start up from cold is this normal?
took it back to dealer and they changed the tensioner for outer belts but its still same runs fine when warm but as soon as its under load when cold it sounds like a bag of spanners
hope you have some ideas
Modern CR engines are pretty quiet when cold, and the 1.6 Ford / PSA HDi particularly so. Pretty sure there's something wrong with this one. You need someone who can read the live data from the engine ECU to try and find out what though.
Crankshaft pulley is well known failure on 2.0 HDi that causes similar symptoms. Not many 1.6s have got to enough miles to know if the problem has carried over - but it's worth a look at the pulley.
PS just because there are no fault codes doesn't mean that there are no sensor values that are out of kilter that would only be picked up by an eagle eyed tech reading the live data as the engine warms up....
Could be the inside of the engine and injectors are gunked up. Have you tried a couple of tanks full of BP Ultimate to clean the inside and injectors ?
The injectors should produce a fine multi-mist spray as well as additional tiny amounts of fuel to counteract diesel rattle. The additive package in BP Ultimate specifically helps counteract diesel rattle in the 1.6 TDCi as well as keeping the inside of the engine clean, hence the reason it's recommended for this particular engine.
Also an engine oil and filter change would help if one hasn't been done recently.
You have to feel for companies like Volkswagen. No sooner had they launched the Golf Mk V, based as closely as it could be on the first Focus, then Ford came up with its even better second generation Focus.
