Are there any known issues with parts at the moment – in particular Dump Valves and MAF (Air Mass Meters)?
We have no known issues with the Dump Valves fitted to any of our vehicles at present; however, from time to time these parts can fail. Air Mass Meters usually fail as a result of water or dirt particles entering the intake tube, therefore it is important to ensure regular cleaning/replacement of the air filter is adhered to. A different type of Air Mass Meter has also been introduced to all TDI models (except Alhambra) with an additional internal tube, which is technically proven to avoid the penetration of water or dirt, and therefore the failure of the Air Mass Meter. It is also worth noting, any modification to the engine management system could result in premature failure of these items.
