I finally managed to replace the Harmony with the Symphony unit in my V6 and what a difference in sound.
I cant believe we didn't do this with our diesel during the 12 years of ownership. Reason I fitted to the V6 was because the diesel has a modified plate on the harmony to hold my sat nav and this is the car we use for towing.
Speaking of the diesel I had noticed it was very flat in acceleration when towing the caravan on our first outing this year, even when solo it had just lost it's punch so a new Bosch MAF was ordered.
It took a couple of weeks to arrive but this morning I fitted it and Oh My! what a difference. The car is back on form again.
Meantime this is rather odd but my under bonnet pump which was very noisy just after I had replaced my in tank pump is now working silently again. Perhaps it's the fuel additive (Millers) I've been using.
I don't use it on every fill up but just occasionally just to keep the injectors etc clean.
