I had my motor re-located on Monday at Daves too.
Was alittle surprised the satnav took me to his home address as i thought he would have a grande garage somewhere, but he told me hes been doing the mod at home lately and thats fine by me. Anyway i took the dog for a walk around the estate and in less than 45 mins it was all done!
He said the drain pipes had blocked up and it was a good job i got to him sooner rather than later as the water level was dangerously close to the motor. He cleared the pipes and also removed the rubber plugs at the bottom as they were the main culprits for trapping dirt and hence causing the blockage.
Daves a delightful chap and tells it like it is. I told him it was ashame he was so far away as im sure he would be my go to guy should anything needed doing on my Zed.
I would recommend having this mod done asap. The drive maybe a tad long for some (mine was 400+ round trip) but its a nice route on the A1 and if anything, the drive helped the engine to loosen up nicely.
At a risk of Hi-jacking the topic, i did notice some wind noise from near the back of the drivers window as i hit motorway speed, Dave said the rubber seals around the area looked abit dry and advised to apply some vaseline to soften it up. Since then, i have read up on similar problems and have ordered some Gummi Pflege as they seem to help restore rubbers, so fingers crossed.
