It's not just me is it? The quality of Bosch parts has seriously fallen over the last 5 years or so.
I considered Bosch parts to be generally good years back. I mean I have bought drills, sanders and well, lots of equipment over the years. It's all been generally good and not really let me down unless it's fair wear and tear.
Then you look at how many parts fitted to cars are Bosch and how often they fail.
Waterpumps with plastic impellors - yeah well done Bosch, that's bound to last!
Plastic/rubber constructed dump valves - Oops, my Turbo just blew a hole in my diaphram!
HT Leads - Burned two in a year. (old car, were damn expensive for the Mazda too)
Spark Plugs - First set just didn't last. On second set the tip was destroyed on one, probably dumped a load of broken bits in my engine (luckily on old car, replaced with NGK's, was perfect after for years).
Wiper Blades - Tried numerous blades on various cars. All seemed to perform poorly. Even the Halfords ones were better, which atually makes me sad. Fitted VAG recommended blades on the Cupra and they are perfect!
Bah....the coil packs are probably made by them as well, looking at the failure rate they must be!
Rant over!
