Catalytic converter going bust?
After leaving the Painted Desert the car threw a check engine light. So instead of going to Roswell and saying hi to the aliens we detoured to Sandy BMW in Albuquerque to have the car checked out. Her are some pics from our trip so far.

Well this is starting to get frustrating. The dealer in Albuquerque couldn't find anything wrong with the car. The service ticket reads as follows...
CEL is on. Had faults stored for catalytic converter that were not currently present. 29F4; 29F5; 2C39; 2C3A. Performed vehicle test. Charged battery. Performed test modules. Results were inconclusive. Cleared faults. Road tested. Recommend customer monitor condition and return to dealer if light comes back on. With that they sent us on our marry way. Well, guess what. We are in Roswell now and wouldn't you know it the car threw another check engine light. So instead of motoring on to Austin tomorow we get to visit the dealer in Lubbock tomorrow. Just great spending another few hours at another dealership. Not my idea of a vacation. |

Bummer about the CEL. Try not to be too paranoid about the CEL if the car is running good.
Your car looks great against the White Sands background. Have a great road trip!

Funny I just had this issue resolved.
I was getting a CEL for the past couple of months, they kept clearing it, saying it ran fine, then it would come back I kept taking it in and they did further testing and found out that the Cats were bad They ordered the cats end of May with an ETA of Mid to Late July as there are no cats in stock in the US or Germany The Shop foreman drove the car and deemed it not a safety issue so they returned the car to us with a CEL. It smelled really bad with the top down, esp on cold starts, it was as if I was catless (reminded me of the smell in my 335i when I had catless downpipes, or my M3 which has High flow cats) There is some strange idle in the RPMs cold mornings when at idle and a slight noticeable decrease in initial acceleration. Took it in again and again, but the Foreman said the issues aren't safety related. I filed for an extended loaner and got denied as 'the car is still safe to drive' I called BMW NA, filed a formal complaint, told them this is ridiculous. I'm paying $$ to use this car every month and you expect me to drive it with a CEL? and the strange idle is 'safe' so I should just 'deal with it'? and the lack of acceleration is 'alright' since the car is already fast? Screw that. My SA was amazing and ended up finding a cat for us and got it installed in the car this week. Drove it last night, no smell, no lack of acceleration, no CEL, beautiful. But nonetheless I'm very angry with BMW. I will be filing a Lemon Law and having my attorney push it hard. Car has had 3 HPFP, 2 of which were during my lease/ownership. Ironically the car was running perfect until I got the HPFP and software recall done. After that, I started having problems left and right I had a Chasis Malfunction, the CEL with the dead cats, and another fuel pump replaced only a month after the recall one! Also the car was leaking oil onto my driveway and has left 2 very large, noticeable stains that I cannot get out. The Z4 was problem free until their recall... I know there are plenty of variables and it's hard to say for sure if it was the recall's fault, but the car had no problems before they did the recall... OP: You need to keep taking it in. Tell them they need to order you a new cat and to do it asap. they're on a huge back order so the sooner you order it, the sooner you'll get it You can drive the car without much issue (except those I experienced and noted above), but nonetheless push BMW to fix it When I go home later I'll get you the part numbers

By law they have to guarantee the emissions control system. Remind them of their obligations.

We made it to Austin without issues. I called the dealer up in Lubbock, but his computer has been down for two days and he cant diagnose squad. So we just drove it to Austin with the cel. Somewhere between Post TX and Hwy 20 the cel went out on its own. Hasnt come on since. Ill talk to my local SA once i m back home.

HPFP failure will equal lean condition in many cases. This will cause EGT to go and sometimes burning up the catalytic converters. The dealers should know this. When i had the HPFP done on both my 335i and 535i, they tested the cats.

S,
Were these the pre-cats in the downpipes or the main Cats under the car?

My HPFP never failed. When I brought the car in for the recall before this trip they only updated the software. No new pump was installed.

we close on our house in Austin (really on Hamilton Pool Road) on July 18th and then the movers are scheduled for the 22nd; look forward to having a Z4 neighbor - you may see my wife or I blasting around the Lake Travis/Bee Cave area often in a black sapphire 35i

hey i have a friend who lives either on or just by hamilton pool road. you might spend a lot of time on 620 as that is where more restaurants are. look for a red z4, that will probably be my wife (she has red hair). actually, it is a bit funny, we went to a walgreens pharmacy the other night and there in the parking lot was another e89 red z4, the only other red z4 i have seen in austin.

Also in Austin
There are more E89 Z4s than you think in the Bee Cave area. I live off Bee Cave Road just down from 71. I just picked up my car about a month ago. It is Orion Silver/Black. I have not seen you guys driving around.
