Hi All, I recently bought a C5 2012, 1.6 hdi, and i m very pleased with the car. I have driven a few times from London to Newcastle and i have been positively surprised by the car as i was a little bit worried that the engine wouldn't have been strong enough for the car. Even though it is not as responsive as the 207 RC i used to own the engine is quite good and i have never felt that i did not have enough power. Moreover, the car is amazingly comfortable, even though it has the normal suspension. Having said all the positive things, i noticed the other day that 3 nuts close to the hinges of the driver's door have started to rust! I checked all the other doors and in general the rest of the car but i have not found signs of rust anywhere else. Has anyone had a similar problem before? What should i do? I suppose that if i go to a citroen dealership they should fix this issue under the corrosion warranty. Thank you for your insights in advance
