Fault Code when towing PO253
The last time I towed my caravan in May, after about an hour, the engine management light came on and the car went into limp mode with the resultant fault code being PO253 (injection pump metering control A low). I changed the fuel filters, air filter, and oil and oil filter and added a bottle of Redex. I've only been using the expensive diesel since then. The car has been running okay without the van in all journeys, with the longest being just over 2 hours. This week I hitched up the caravan and once again after about one hour, the light came on again and and the same code PO253 showed up. I deleted the code which removed the warning light, but it came back on within 10 minutes. I sat for 5 minutes or so, deleted the code once more, light went out and I drove home about fifty miles with the car running normally.
Something similar happened to my previous car, a Mondeo Estate which never had a problem until towing. I spent three hundred pounds on that without the garage finding the problem.
My Antara is 2012 model, 2.2 CDTI, 4x4.
Anyone any ideas?
