| Video Discription | After having some trouble recently with the Passat, I've made a quick video just to demonstrate an easy fix that may work for anyone else with a similar issue. After harsh acceleration, the car would go into what is known as limp mode. If the ECU detects a fault with the car (such as over boost in this case) the cars computer will shut off the turbo completely and reduce throttle by 50% effectively giving the car around 40bhp. This is enough to get home safely. After plugging in VDCS, I was able to determine the trigger of the limp mode being an over boost. Over boost in 1.9 TDi engines typically occurs due to stuck VNT vanes inside the turbo, that continue to boost after throttle has been released, thus triggering a safety response from the ECU in order to protect the engine. These vanes become sticky or stuck due to years of carbon build up from the exhaust, but can easily and affordably be addressed using a strong grease remover such as Mr Muscle, conventionally used to remove stubborn grime from ovens. This may save you from the expense of a brand new turbo, so is always worth giving a try before biting the bullet on an expensive repair bill. 2m x 3mm silicone tubing at £0.50 per meter 1 x Mr Muscle oven cleaner at £4 This took around 2.5 hours from start to finish. Thanks for watching. |
