My R reg Galaxy has started losing power again - especially noticeable when going up hills at speed (or trying to!) - which makes me think the MAF sensor needs replacing again. It was last replaced just over 18 months ago.
Does anyone know how difficult it is to replace the sensor (or how long it takes)? Is it a job that only main dealers can do?
Also, what causes the sensor to deteriorate so quickly?
Thanks.
PS Anyone know if new Galaxies suffer from the same (design) problem? It seems a real weakness.
