because your car has a bad brake light switch

Why would the brake light switch make the glow plug light flash?

A flashing glow plug light is also a form of Check Engine light... best bet is to have the car scanned for codes....especially if there are engine running symptoms associated with the light.

My random interweb guess: a QA issue... which also triggers the flashing glowplug light.

You have to scan it for fault codes. VCDS is preferred, but generic OBDII should be sufficient in this case. The flashing light means there's a severe engine management fault.

The brake light bulbs or switch failure will do it as well, do draw your attention to a potentially dangerous condition.

The other ones I know of so far are the #3 lift sensor injector and the tps throttle positioning sensor. As said you'll really need to scan it to see what the actual issue is.

You need to scan for codes. That's it. Without that its just stabbing in the dark...

Obvious maybe, but did you reconnect the glow plugs? Was the flashing G/P light and starting issues there before pulling the head?

I think they just like trying to fix an electrical problem with a large hammer.

That CEL (check engine light) is just a kid in class waving her hand trying to get you attention because she has the answer. You need to have the codes read. Some places will read them for FREE. Try Autozone or Advanced Auto Parts. Get the exact code (like P0123) not just their translation into English and post it back here.
