Problem with water pump on recent 1.9 TDi, 2.0 TDi and 2.0 E engines
Do you happen to have a car made recently (up to 5 years ) by VAG
(Audi VW, Skoda and Seat) fitted with either a 1.9 L TDi, 2.0 TDi or 2.0 E engine ? Then read this carefully. The water pump design was changed by VAG to save some money in a way that could be catastrophic to your engine. It is a volumetric pump so the propeller or fan material is now made of plastic and it is mounted on the shaft through a friction fit. Any engineer knows that a friction fit between a plastic fan and a steel is not bound to last long. We have obserrved that juste after three years, several pumps start to slip leading to a variety of symptoms that are not pointing necessarily to the pump progressive failure. VAG has done a terrible design error and they should be ask to change their axis with a grooved one which will then be strong enough. Having an Audi 80 with a 1.9 TDi which is just a fantastic car with a great engine, I feel that VAG should never make this kind of stupid design error just in order to save a bit of money. Moreover, I would even not accept that error from my students. |

The pump *has* been changed for one with a metal impeller. I've never heard of this problem with TDI engines either- though it's common on the 1.8T. |

I had the problem with the plastic impeller and Audi replaced it FOC for a new water pump with metal impeller. |

I have a 2001 A4 1,8TS (older 8D chassis) and am trying to figure out which impeller I have. /Robert |
