hi all,
just been offerd a 2.0 hdi picasso, 05 reg
when it gets up to temp it runs rough /lumpy but runs ok when cold,

anyideas what itcouid be?
im thinking H/g but theres no oil in coolant and its not using coolant

Injector wiring loom braking down when it gets hot or something else electrical braking down when the engine physically gets hot?

Injectors blocked? Run a fast fuel return test.

cheers just had alook at it, dosent sound well,
and at £2700 iwill leave it where it is me thinks,
he declined my offer of £1500
