Selling my sons imaculate BMW 116i as Spares or repairs. Car runs and drives, but engine down on power. Suspect timing chain or Vonos units. Trouble code P13B4. Vonos solenoids and Cam sensors replaced, last weekend, but still no joy. Needs stripping/ further tests, but I don't have time to do it. Car is in imaculate condition inside and out. Full grey leather interior. Recent new tyres, alloy wheels in great condition. New rear discs and pads. Recent spark plugs,coil packs, cam cover gasket and oxygen sensor replacements. Long Mot August 25. Vehicle can be driven away, but max speed c60 mph and Engine warning light on. Full service history and well maintained. Grab yourself an excellent project car. We are 2 miles away from M1, junction 18 Crick.
