PSA’s 1.6 HDi engine was repeatedly mentioned as a particularly problematic job with some respondents noting difficulty in removing the carbon build-up in the oil feed pipes. It’s thought that if the engine has been operated with a low oil level, a high concentration of carbon in the oil can lead to the blockage of the in-line filter, oil cooler and main oil filter, which will eventually bring on premature turbocharger failure. Other problem areas highlighted in the GW reader survey included poor quality non-OE turbocharges and difficulties in obtaining new feed pipes.
27 per cent mostly fit new OE turbochargers while 20 per cent tend to fit non-OE turbos. The remaining 53 per cent say it depends on their customer’s budget. When it comes to remanufactured turbos, 47 per cent would only ever fit an OE remanufactured unit from a “trusted supplier” and 42 per cent would favour the non-OE remanufactured alternative.
