I have owned my 2001 P38 4.6L Vogue for ten years. I have suffered many of the usual P38 problems with EAS, remote receiver, crankshaft position sensor etc but nothing major until it started overheating last year. It's either the head gasket or the cylinder liners but was fixed with some liberal application of Steel Seal. This fixed the overheating problem with combustion gases entering the cooling system but put a load of sludge into the radiator & heater matrix which led to more overheating problems & a non-functioning heater.
I was very happy to meet @Gilbertd in person as he lives only 10 miles from where I work. He introduced me to this forum & has been doing some work on my car. The Nanocom fixed some minor irritating problems with the headlight warning & interior light not working. The new radiator has fixed the overheating but the leaking sludged up heater matrix proved more challenging so has been removed & bypassed for the moment so I don't have a heater at present but in summer this isn't a problem. Replacing the heater matrix requires complete removal of the dashboard & is a 2-3 day job that will have to wait until next month. The AC has been recharged so I can be icey cool when it's hot outside.
I acquired the car as part of a divorce settlement ten years ago. My initial plan had been to sell it it but after I drove it for a week or two I fell in love with it. It's still the nicest car I have ever driven. I love the driving position, the visibility, the manoeuvrability, the performance etc The fuel consumption of 18mpg is the price I have to pay for driving around in a £50,000 car. It's not my daily driver but I do use it regularly. We have had countless journeys to & from our cottage in Brittany heavily loaded in both directions. We are now resident in France & spend over half our time there so the P38 has been re-registered on French plates. There was a one off cost of registration of €500 but there is now no equivalent of road tax in France so I save over £300 each year. The equivalent of the MOT (Côntrole Technique) is every two years. I considered an LPG conversion but first I am going to experiment with E85 (85% ethanol 15% petrol) which is available in France at half the price of petrol.
