Re: Thumping noise at low speeds
Scottish XF,
Ring Chrysler Assistance (CA) 0800 777146. I have nothing but praise for them after our dealer in Farnham forgot to put back on O-Ring on our PT Cruisers cooling system.
CA sent a mechanic to the house at 07:00 and he identified the problem as an air-lock and he bled and pressurised the system. Since this didn't cure the problem I called CA again a couple of days later. CA took my details and within an hour our car was collect from my work place and I had a similar-sized hire car delivered. Chrysler Weybridge found the fault, fixed it and delivered the car back over the weekend. They had cleaned it inside and out.
